PNEUMATIC-CONVEYER HO'PPER.

Application filed October 5, 1916.

To all whom t may concern Be it known that I, Louis C. VANDERLIP, a citizen of the United States, residing at Elkhart, Elkhart county, Indiana, have invented new and useful Improvements in Pneumatic-Conveyer Hoppers, of Which the following is a specification.

This invention relates to pneumatic conveyors, and particularly to the hopper fitting, or section, by which the material to be conveyed is introduced to the conveyer conduit interior.

One of the objects of my invention is the production of a hopper fitting of the kind described which is eifectually protectedagainst Wear at all interior points by improved Wear liners. Another object is the improved manner of inserting and removing the wear liners from the hopper fitting. Other objects of the invention Will be mentioned and described herein from time to time.

In pneumatic conveyers handling abrasive materials, such as ash and the like, Whether of the suction fan or blast type, substantial Wear on the interior of the con duit, bends, elbows and hopper fittings is In the majority, or a great many. of the pneumatic conveyers noiv being used heavy unlined cast iron pipe is used for the main conduit which, when laid in a horizontal or inclined position, Wear most rapidly at the bottom of the bore thereof and when so Worn may be rotated for a fe'vv degrees to bring into position a comparatively unvvorn portion of the pipe. In this ivay the pipe line may be rotated by degrees several times until one complete revolution thereof has been made, thereby materially increasing the utility thereof. To meet this practice I provide an improved form of T, or hopper fitting, having tubular Wear liners which, when Worn on the bottom portion of the bore thereof by the abrasive action of the conveyer contents, may be partially rotated Within the hopper fitting body coincident with the partial rotation of the pipe conduit sections to which the hopper body is bolted.

The preferred embodiment of my invention is disclosed in the accompanying drawings in which similar numerals refer to similar members and parts of members, and in Which Figure 1 is a side sectional elevation thereof; and Fig. 2 is a section on the line 2--2 of Fig. 1.

Referring to the drawings in detail, the

Specification of Letters 1 atent.

Serial No. 123,805.

numeral 1 indicates a tubular hopper fitting body member which is provided with end ianges 2 and 3 for connection With sections of a pneumatic conveyer line. The numeral 4 indicates lan elongated opening formed in the top of the body member 1 extending longitudinally thereof, terminating adjacent the end flanges 2 and 3, and preferably having a rectangular orifice. In Width, the opening 4 is substantially equal to the bore diameter of the body member 1 to permit of the ready insertion and removal of the tubular Wear liner sections hereinafter described. The` numeral 5' indicates a cover plate detachably fastened over the opening 4 by bolts 6, 6, the latter being connected with the flanges 7, 7, of member 1. ",Ihe cover plate 54 is provided with the hopper 8 for material introduction to the fitting interior the hopper opening being normally closed by the removable cover 9, the latter being provided with a handle 10, said hopper opening having an area substantially less than the area of the body member branch opening 4.

The plate 5 is also provided With a spout latter being surrounded by the rim, or flange,

16 and into which the hopper .spoilt 1.1 prof jects. When the plate 5 is removed Wear sections l2 and 13 are first placed in position Within the member 1, section 14 following and serving also as a key liner.

I claim:

1. A device of the class described comprising a tubular body member provided with an elongated branch opening; a Wear lining removably arranged Within said body member and consisting of a plurality of sections arranged end to end and adapted for insertion and removal through said body member branch opening; an elongated cover plate detachably fastened over said body member branch opening, said plate being provided With an opening the area whereof is substantially less than the area of said body member branch opening; and a removable cover for said branch opening cover plate opening.

2. A device of the class described comprising a tubular body member' provided with a branch opening; a removable Wear liner arranged Within said tubular body member; and an apertured plate detachably covering said body member branch opening, said plate being provided With a spout on its under side which is adapted to coperate with said aperture to establish communication between the interior and exterior of said body member.

3. A device of the class described comprising a tubular body member provided with a branch opening; a substantially cylindrical Wear lining removably arranged Within said body member and consisting of a plurality of sections arranged end to end, one of said Wear sections being laterally apertured; an apertured cover plate detachably fastened over said body member branch opening, said cover plate aperture being in registration with the lateral aperture in said Wear lining section; and a removable cover for said branch opening cover plate opening.

4. The combination Wit-h a tubular body member provided with a branch opening, of a cylindrical Wear lining removably arranged Within said body member and composed of a plurality of cylindrical sections arranged end to end, one of said Wear sec- .tions being laterally apertured; an apertured cover plate detachably fastened over said body member branch opening, said cover plate aperture being in registration with the lateral aperture in said apertured Wear lining section; and a removable cover for said branch opening cover plate opening.

5. A device of the class described comprising a tubular body member provided with a lateral opening; a tubular Wear lining removably arranged Within said body member, said lining being laterally apertured; and an apertured plate detachably fastened over said body member lateral opening, said plate aperture being in registration With said wear lining lateral aperture, said plate being provided with a spout which is in eoperation With said wear lining lateral aperture. l

6. A device of the class described comprising a tubular body member provided with a lateral opening; a tubular Wear lining removably arranged within said body member and provided with a branch opening; and an apertured plate detachably fastened over said body member lateral opening, said plate being provided with a spout which projects into said Wear lining branch opening and is adapted to coperate With said plate aperture to establish communication between the body member interior and exterior.

7. A device of the class described comprising a tubular body member provided with a lateral opening; a tubular Wear lining removably arranged Within said body member, said lining being kprovided With a Arimmed branch opening; and an apertured plate detachably fastened over said body member lateral opening, said plate aperture being in registration with said rimmed branch opening of said Wear lining.

.8. The combination With a tubular body member provided with a branch opening and an apertured cover plate detachably fastened over said branch opening, of a cylindrical Wear lining removably arranged Within said body member and composed of a plurality of cylindrical sections arranged end to end, one of said Wear sections having a branch opening which is in registration with the aperture in said cover plate.

In testimony whereof I have hereunto aiixed my signature this 8d day of October, 1916.
